selectString is not a function error in RestDataSource transformResponse

[pablocarle]

Hi Isomorphic,

I'm following the documentation for configuring RestDataSource using Spring controllers. I'm getting the error in the title when performing a fetch operation.

The JSON Response is as follows (shown in Dev console), which pretty much is the same format as in the RestDataSource javadoc:

{"response":{"status":0,"startRow":0,"endRow":1,"totalRows":1,"data":[{"apellido":"last_name","nombre":"name","username":"uname","email":"carlep@live.com.ar","password":""}]}}

The DataSource definition:

package com.sgrvg.client.main.ds;

import com.smartgwt.client.data.DSRequest;
import com.smartgwt.client.data.OperationBinding;
import com.smartgwt.client.data.RestDataSource;
import com.smartgwt.client.data.fields.DataSourcePasswordField;
import com.smartgwt.client.data.fields.DataSourceTextField;
import com.smartgwt.client.types.DSDataFormat;
import com.smartgwt.client.types.DSOperationType;
import com.smartgwt.client.types.DSProtocol;

/**
 * @author pabloc
 * 
 * DataSource para administracion de usuarios (modificar datos / password)
 *
 */
public class UserDS extends RestDataSource {
	
	private static UserDS instance = null;
	
	public static UserDS getInstance() {
		if (instance == null) {
			instance = new UserDS();
		}
		return instance;
	}
	
	private UserDS() {
		super();
		
		setClientOnly(Boolean.FALSE);
		
//		FIELDS
		DataSourceTextField username = new DataSourceTextField("username", "Usuario", 50, true);
		DataSourceTextField nombre = new DataSourceTextField("nombre", "Nombre", 45, true);
		DataSourceTextField apellido = new DataSourceTextField("apellido", "Apellido", 45, true);
		DataSourceTextField email = new DataSourceTextField("email", "E-Mail", 255, false);
//		En cambio de password poner como hidden y luego de la validacion modificarle el valor y hacer el saveData
		DataSourcePasswordField currentPassword = new DataSourcePasswordField("password", "Password", 50, true);

		setFields(username, nombre, apellido, email, currentPassword);
		
//		DSRequest properties
		DSRequest updateRequest = new DSRequest(DSOperationType.UPDATE);
		updateRequest.setHttpMethod("PUT");
		updateRequest.setContentType("application/json");
		
//		OPERATION BINDINGS
		OperationBinding fetch = new OperationBinding(DSOperationType.FETCH, "service/user");
		fetch.setDataProtocol(DSProtocol.GETPARAMS);
		fetch.setDataFormat(DSDataFormat.JSON);
				
		OperationBinding update = new OperationBinding(DSOperationType.UPDATE, "service/user");
		update.setDataProtocol(DSProtocol.POSTMESSAGE);
		update.setDataFormat(DSDataFormat.JSON);
		update.setRequestProperties(updateRequest);
		
		setOperationBindings(fetch, update);
		
	}
}

The controller:

	@RequestMapping(value="/user", method=RequestMethod.GET, produces=MediaType.APPLICATION_JSON_VALUE )
	@ResponseBody
	public DSResponse getUserData(final HttpServletRequest request, Principal principal) {
		final String currentUser = principal.getName();
		
		Usuario usr = usrManager.encontrarUsuarioPorUsername(currentUser);
		
		return new DSResponse(usr);
	}

The issue happens in the transformResponse method

In compiled mode, the error happens in ISC_DataBinding.js (line 2721 if it helps)


Any help would be greatly appreciated.

Set dataFormat to JSON on the RestDataSource as a whole. Setting it on just some operationBindings is not enough.

Excellent, it's working now. Many thanks!
